Split windshield assembly for recreation vehicle

ABSTRACT

An improved split windshield assembly includes a retainer clip constructed of a flexible material, and a flexible, hollow clamp. The clip is for being attached to an upper portion of at least one of the front support posts of a recreation vehicle for releasably holding the upper windshield panel in a closed position. The hollow clamp has a base, and first and second hollow arms. The base is fixedly attached to the lower windshield panel at a lower portion thereof. The first and second hollow arms have opposed, closely spaced-apart inside surfaces which define a longitudinally-extending, windshield-holding channel. The windshield-holding channel engages and holds a curved top edge of the upper windshield panel when the upper windshield panel is in the open position.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

This invention relates to a windshield assembly for attachment to a recreation vehicle, such as a golf cart. The invention relates particularly a windshield assembly including an improved means for attaching the windshield to the golf cart.

Most conventional golf carts have a canopy supported by a pair of front and back support posts. Additionally, these golf carts generally include a split windshield having an upper panel and lower panel connected together by a hinge. Various attachment devices serve to attach the split windshield to the front support posts of the golf cart. The upper panel of the windshield is moveable from a closed position wherein air flow is shielded from the face of the driver, to an open position wherein air flows freely above the lower panel and through the support posts to the driver while the cart is in motion. When in the open position, the upper panel pivots outwardly from the normal plane of the windshield and overlies the lower panel. A first attachment device holds the upper panel in the closed, air-shielding position, and a second attachment device holds the upper panel in the open, air-flowing position.

A split windshield assembly, as described generally above, is known in the art. Many of these windshield assemblies, however, include attachment devices which are inadequate for effectively holding the upper panel of the split windshield in the open and closed positions while the cart is in motion. According to one prior art windshield assembly, each of the first and second attachment devices have a pair of relatively thin arms for engaging either the front support posts or a curved top edge of the upper panel. The attachment devices are constructed of a hard resinous material, and require frequent replacement due to breakage and cracking of the arms. In addition, because the attachment devices are relatively hard or rigid, they do not effectively grip and hold the upper panel in the desired position while the golf cart is in motion.

A windshield assembly of the present invention over comes the drawbacks of the prior art by providing respective first and second flexible attachment devices which resist breakage and cracking. The devices securely hold the upper panel in both the open and closed positions, and do not require frequently replacement due to wear and damage.

DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, a windshield assembly according to the present invention is illustrated in FIG. 1 and shown generally at reference numeral 10. The windshield assembly 10 is designed particularly for attachment to a pair of laterally spaced and vertically extending front support posts 11 and 12 of a recreation vehicle "V", such as a golf cart.

The windshield assembly 10 includes a lower windshield panel 13 and an upper windshield panel 14. Preferably, the panels 13 and 14 are made of either clear or tint, extruded methyl methacrylate or acrylic, and are approximately 4.5 mm thick. The lower windshield panel 13 is permanently attached to respective lower portions 11a and 12a of the front support posts 11 and 12 by a pair of elongate post fixtures 16 and 17. The post fixtures 16 and 17 are well known in the art, and are typically constructed of a polyvinyl chloride material. Preferably, the upper windshield panel 14 is connected to the lower windshield panel 13 by a laterally extending hinge 15. The hinge 15 allows movement of the upper windshield panel 14 from a closed position (See FIGS. 1 and 2), generally coplaner with the lower windshield panel 13, to an open position forward of and beside the lower windshield panel 13 (See FIG. 3). The hinge 15 is preferably constructed of a urethane elastomer center section, and side body parts formed of a high-impact acrylic. The hinge 15 may be that manufactured by Westedge, Inc. under the trademark "Flex-Fold."

Retainer Clip

When in the closed position as shown in FIGS. 1 and 2, the upper windshield panel 14 is held adjacent to respective upper portions 11b and 12b of the front support posts 11 and 12 by one or more retainer clips 21 and 22. Preferably, a single retainer clip 21,22 is located on each of the respective front support posts 11 and 12. The retainer clips 21 and 22 are constructed of a flexible synthetic resin material, such as neoprene (rubber), urethane, EDPM, or vinyl. Preferably, the retainer clips 21 and 22 are constructed of a synthetic material manufactured by BF Goodrich under the trademark "Estane."

The retainer clips 21 and 22 are formed by extruding the resin material through a die to produce a length of material, and then cutting the length at predetermined intervals. For achieving sufficient holding strength, the retainer clips 21 and 22 are cut approximately 4-8 cm in length. In addition, an ultraviolet inhibitor may be incorporated in the resin material to protect the retainer clips 21 and 22 from sun damage and wear.

The retainer clip 22 for attachment to support post 12 is described in detail below with reference to FIGS. 4-8. The components and features of the retainer clip 22 and support post 12 are identical to that of retainer clip 21 and support post 11, respectively. Thus, any description of retainer clip 22 applies equally to retainer clip 21, and clip 21 will not be further described.

Referring now to FIGS. 4-8, retainer clip 22 includes an attachment member 23 and a windshield retaining member 24. The attachment member 23 has an outer surface 23a for engaging and being attached to a front portion 12c of the front support post 12, and an inner surface 23b for engaging an inside face 14a of the upper windshield panel 14 when the upper windshield panel 14 is in the closed position (See FIGS. 7 and 8). As best shown in FIGS. 5 and 6, when attached to the front support post 12, a first side end 23c of the attachment member 23 is located generally at an inside edge 12d of the support post 12, and a second side end 23d of the attachment member 23 is located just beyond an outside edge 12e of the support post 12. According to one preferred embodiment, the attachment member 23 is approximately 3-4 cm wide, and 0.5 cm thick.

Preferably, the attachment member 23 further includes an extension 28 for engaging an inner side portion 12f of the front support post 12. The extension 28 is integrally formed with the first side end 23c of the attachment member 23, and extends approximately 2-3 cm in width substantially perpendicular to the plane of the attachment member 23. As best shown in FIG. 4, the extension 28 may include a small pilot hole 31 for receiving a metal screw 32, such as a #6 interior trim screw. The metal screw 32 passes through the extension 28 and front support post 12 to permanently attach the retainer clip 22 to the support post 12. Additionally, the support post 12 may have a corresponding pilot hole 33 formed therein to guide the screw 32 into the support post 12. According to a second embodiment, the retainer clip 22 may be attached to the front support post 12 by any suitable rubber adhesive. According to a third embodiment, the clip 22 may be formed with a clip fastener (not shown) having spaced-apart, slightly resilient arms for frictionally engaging the support post 12, and thus attaching the clip 22 to the post 12.

The windshield retaining member 24 is integrally formed with the second side end 23d of the attachment member 23, and normally overlaps the attachment member 23 in a biased condition. When biased or nonflexed, the windshield retaining member 24 resides in slightly spaced, overlying relation to the attachment member 23, thereby defining a slot 30 between the attachment member 23 and the windshield retaining member 24. The width of the windshield retaining member 24 is approximately 3-4 cm, and preferably corresponds to the width of the attachment member 23.

As best shown in FIG. 7, the attachment member 23 and the windshield retaining member 24 of the retainer clip 22 cooperate to securely hold the upper windshield panel 14 in the closed position within the slot 30 while the golf cart is in motion. FIGS. 5 and 7 illustrate the windshield retaining member 24 in a normal, biased position. To release the upper windshield panel 14 from the slot 30, the windshield retaining member 24 is flexed from the biased position to a panel release position generally perpendicular to the plane of the upper windshield panel 14. FIGS. 6 and 8 illustrate the windshield retaining member 24 in a flexed, panel release position, permitting movement of the upper windshield panel 14 from the closed position to the open position. To provide a sufficient biasing force, the windshield retaining member 24 is preferably about 0.8 cm thick at its proximal end 24c, and about 0.5 cm thick at its distal end 24d.

First and second hand grips 26 and 27 are preferably formed on an outer surface 24a of the windshield retaining member 24 to receive pressure applied by the thumb or forefinger of the user. The hand grips 26 and 27 allow the user to easily flex the windshield retaining member 24 from the biased position outwardly to the panel release position. According to one preferred embodiment, the hand grips 26 and 27 protrude outwardly approximately 0.5 cm from the plane of the windshield retaining member 24. The first hand grip 26 is located generally at the distal end 24d of the windshield retaining member 24, and the second hand grip 27 is located generally at a proximal end 24c of the windshield retaining member 24.

Referring now to FIGS. 1-3 and 9-10, the windshield assembly may further include at least one flexible, hollow clamp 41 located at the base of the lower windshield panel 13 (See FIGS. 1-3). Preferably, the windshield assembly includes two identical clamps 41 and 42. The clamps 41,42 serve to grip an outwardly curved top edge 14c of the upper windshield panel 14 to thereby hold the panel 14 in the open position while the golf cart "V" is in motion. Preferably, the clamps 41 and 42 are constructed of a flexible synthetic resin material, such as neoprene rubber, and include an ultraviolet inhibitor to protect the clamps 41,42 from sun damage and wear. According to a preferred embodiment, the clamps 41,42 are approximately 6-7 cm long and 2-3 cm wide, respectively.

The clamps 41 and 42 are described in detail below with reference to clamp 42. Since clamp 41 is identical to clamp 42, it will not be further described.

As best shown in FIGS. 9 and 10, the clamp 42 includes a base 43, and first and second flexible hollow arms 44 and 45. The base 43 is attached to the lower windshield panel 13 at a lower portion 13a of the panel 13 (See FIGS. 1-3) by a suitable rubber adhesive. Preferably, the base 43 is approximately 0.3-0.5 cm thick. The first and second hollow arms 44 and 45 are integrally formed with the base 43, and extend outwardly approximately 3-4 cm from the base 43. The arms 44 and 45 have opposed, closely spaced-apart inside surfaces 44a and 45a which define a longitudinally-extending, windshield-holding channel 46. According to a preferred embodiment, the inside surfaces 44a and 45a of the respective flexible arms 44 and 45 are spaced-apart approximately 0.3 cm. The windshield holding channel 46, defined by the spaced-apart inside surfaces 44a and 45a, engages and holds the curved top edge 14c of upper windshield panel 14 when the upper windshield panel 14 is in the open position (See FIG. 3).

The first and second hollow arms 44 and 45 preferably include respective rib supports 48 and 49 integrally formed with the opposing inner walls of the hollow arms 44 and 45. The rib supports 48 and 49 supply added holding strength to clamp 42, and extend in a plane parallel to and spaced-apart from the base 43. Additionally, to further increase its holding strength, the clamp 42 may include windshield grips 51a, b and 52a, b (See FIG. 10) integrally formed with respective inside surfaces 44a and 45a of the first and second arms 44 and 45. The grips 51a, b and 52a, b act to further secure the curved top edge 14c of the upper windshield panel 14 between the first and second arms 44 and 45 when the upper windshield panel 14 is in the open position.
